Hypothesis-Testing Demands Trustworthy Data—A Simulation Approach to Inferential Statistics Advocating the Research Program Strategy
In psychology as elsewhere, the main statistical inference strategy to establish empirical effects is null-hypothesis significance testing (NHST). The recent failure to replicate allegedly well-established NHST-results, however, implies that such results lack sufficient statistical power, and thus feature unacceptably high error-rates. Using data-simulation to estimate the error-...

The structure and dynamics of the ceo's “small world” of stakeholders. An application to industrial downsizing
Stakeholder theory highlights that a CEO must perform a social responsibility towards multiple stakeholders (employees, politicians, journalists, citizens, etc). These stakeholders constitute a political system and the CEO develops a political strategy to deal with the claims of the different actors. This article mobilizes social network analysis and the complex networks theory to...

Entrepreneurial orientation and SME performance across societal cultures: An international study
The concept of entrepreneurial orientation (EO) is universally applicable, and many empirical studies report a positive relationship between EO and performance in different national contexts. Empirical research, however, scarcely addresses which country-level contingencies affect the EO–performance link. Building on two secondorder factors of societal culture—performance-based...

Understanding stigma: a communal perspective for overweight consumers
This work provides a deeper understanding of how overweight stigma operates in a collective context. I investigate a French online community of overweight women. First, I identify the elements that contribute to experiencing the stigma of overweight and how they interact with consumption. Then, I look at the role of the community for consumers that have distanced themselves from the...

Using Bayesian hierarchical parameter estimation to assess the generalizability of cognitive models of choice
To be useful, cognitive models with fitted parameters should show generalizability across time and allow accurate predictions of future observations. It has been proposed that hierarchical procedures yield better estimates of model parameters than do nonhierarchical, independent approaches, because the formers’ estimates for individuals within a group can mutually inform each other....

Different strategies for evaluating consumer products: attribute-and exemplar-based approaches compared
Consumers’ purchase decisions depend on whether a product is perceived as a bargain or as overpriced. But how do consumers evaluate sales prices? The standard approach in economics, psychology, and marketing suggests that consumers’ estimates are best described by a attribute-based or piecemeal strategy that integrates information about products in a linear additive fashion. Here, we...

Selecting decision strategies: the differential role of affect
Many theories on cognition assume that people adapt their decision strategies depending on the situation they face. To test if and how affect guides the selection of decision strategies, we conducted an online study (N = 166), where different mood states were induced through video clips. Results indicate that mood influenced the use of decision strategies. Negative mood, in...

An introduction to Bayesian hypothesis testing for management research
In management research, empirical data are often analyzed using p-value null hypothesis significance testing (pNHST). Here we outline the conceptual and practical advantages of an alternative analysis method: Bayesian hypothesis testing and model selection using the Bayes factor. In contrast to pNHST, Bayes factors allow researchers to quantify evidence in favor of the null...

An information theory account of preference prediction accuracy
Knowledge about other people's preferences is essential for successful social interactions, but what exactly are the driving factors that determine how well we can predict the likes and dislikes of people around us? To investigate the accuracy of couples' preference predictions we outline and empirically test three hypotheses: The positive valence hypothesis predicts that...

A generalized distance function for preferential choices
Many cognitive theories of judgement and decision making assume that choice options are evaluated relative to other available options. The extent to which the preference for one option is influenced by other available options will often depend on how similar the options are to each other, where similarity is assumed to be a decreasing function of the distance between options. We...

How outcome dependencies affect decisions under risk
Many economic theories of decision making assume that people evaluate options independently of other available options. However, recent cognitive theories such as decision field theory suggest that people’s evaluations rely on a relative comparison of the options’ potential consequences such that the subjective value of an option critically depends on the context in which it is...

Der Mythos Konzernzentrale
Sie werden als Zeichen von Leistung und Erfolg bewundert, aber auch als Ort der Machtkämpfe und Bürokratie misstrauisch beäugt. Haben Konzernzentralen in Zeiten der digitalen Vernetzung und der Globalisierung noch einen Sinn?

Schweizer M&A-Markt 2014 : Auf dem Gipfel angekommen ?
Das Jahr 2014 war ein Rekordjahr auf dem Schweizer M&A-Markt. So stieg die Anzahl der Transaktionen um 33% von 315 im Jahr 2013 auf nunmehr 420 an. Auch der Fünf-Jahres-Vergleich zeigt, dass die Anzahl angekündigter Deals die Werte aus den Jahren 2010 bis 2012 übertraf. Noch positiver fällt der Blick auf die Entwicklung des Dealvolumens im vergangenen Jahr aus, das zuletzt 188,1...

Rigorously testing multialternative decision field theory against random utility models
Cognitive models of decision making aim to explain the process underlying observed choices. Here, we test a sequential sampling model of decision making, multialternative decision field theory (MDFT; Roe, Busemeyer, & Townsend, 2001), on empirical grounds and compare it against 2 established random utility models of choice: the probit and the logit model. Using a within-subject...

A hierarchical Bayesian model of the influence of run length on sequential predictions
Two models of how people predict the next outcome in a sequence of binary events were developed and compared on the basis of gambling data from a lab experiment using hierarchical Bayesian techniques. The results from a student sample (N = 39) indicated that a model that considers run length (“drift model”)—that is, how often the same event has previously occurred in a row—provided a...

Genetic influences on dietary variety - Results from a twin study
The heritability of variety seeking in the food domain was estimated from a large sample (N = 5,543) of middle age to elderly monozygotic and dizygotic twins from the “Virginia 30,000” twin study. Different dietary variety scores were calculated based on a semi-quantitative food choice questionnaire that assessed consumption frequencies and quantities for a list of 99 common foods....
